My car is a sierra 2.0 DOHC, I'ma mechanic and welder, questions I have are about the placement of the alternator and power steering pump, collector item no problem because I can change them without problem.The turbo issue, my neighbor has put in his DOHC turbo, lots of work, lots of money and little fiabilidad.He found a complete mechanical and electronic one escort rs 2000 for little money, but before buying my question was to attach the Shapire not want to spend the money and then the engine stays in the garage gathering dust.
